A study on reflection property of fiber tilted grating
摘要
对具有倾角的光纤光栅的反射特性进行了研究 .得到了耦合系数随倾角变化的关系式 .随着倾角的增大
耦合系数会减小
反射谱的中心波长会向长波长方向移动
而反射谱的形状不发生改变 .
Abstract
In this paper
we investigate the reflective spectral response of a optical fiber tilted grating structure with the coupled wave equation. Because the period of fiber tilted grating is larger than that of non tilted grating
the central wavelength of reflectivity is shifted to long wavelength side.
